11. Vomiting. 
This is sometimes met with in cattle, but never in horses. 
Causes. — It is generally caused by some irritation of the 
fourth, or true digestive part of the stomach, or it may be 
caused by eating some bones, old clothes, or a boot, or some- 
thing of that kind. Sometimes it is caused by nails which 
are taken into the rumen with food. Often after an animal 
is slaughtered there are nails and rubbish found in the 
stomach. 
Treatment. — Give a physic consisting of 
Epsom Salts 1 pound. 
Brown Sugar ^ pound. 
Salt 2 dessertspoonfuls. 
Mix in a quart of lukewarm water and give as a drench. 
This generally gives relief, but if not, give : 
Raw Linseed Oil 1 pint. 
Mix and give as a drench every second day until the 
animal gets relief. Feed soft food and give lukewarm water 
to drink for a while. In cases where this treatment does not 
give relief and it is certain that there is something in the 
stomach, perform the operation of rumenotomy and take it 
out. 
12. Hair Balls in the Rumen or Paunch. 
Causes. — They are caused by animals licking each other 
in the spring when the hair is loose. The hair collects in a 
ball in the stomach. 
Symptoms. — The animal soon stops chewing its cud, and 
has slight spells of bloating. It does not feed well and soon 
falls off in condition. 
Treatment. — Give a physic of 
Epsom Salts 1 pound 
Bicarbonate of Soda 2 dessertspoonfuls. 
Ginger 2 dessertspoonfuls. 
Mix in a quart of lukewarm water and give as a drench. 
Give this drench once a week, and if it does not relieve and 
it is thought that there is a hair ball in the stomach, then, 
as a last resort, perform the operation of rumenotomy. 
There have been cases known in which snakes, from 
three to four feet long, have been found in the stomach of 
Sweet Spirits of Nitre 
Bicarbonate of Soda .
